Abstract

Photovoltaic devices based on electrochemically synthesized poly(3-methylthiophene) PMeT were constructed and characterized. The charge mobility for positive carriers of this polymer is quite high, 4 x 10^-4 cm²/Vs, being attractive for optoelectronic devices. In single layer photovoltaic devices with PMeT active layer electrochemically deposited onto indium-tin oxide substrate with aluminum as top electrode we have obtained short-circuit current density of 0.31 A/m², open-circuit voltage of 1 V and power conversion efficiency of 0.14% at 100 W/m² white light irradiance.
